About this item

  • The TP4056 is a complete lithium-ion battery charger for single-cell batteries, compatible with both USB power supply and adapter power supply.
  • The TP4056 charging module has a fixed charging voltage of 4.2V and allows the charging current to be externally adjusted using a resistor. Once the charging current reaches the final float voltage and drops to 1/10 of the set value, the charging cycle is automatically terminated.
  • When the input voltage (from an AC adapter or USB power supply) is disconnected, the TP4056 enters a low current state to minimize battery leakage current to below 2uA. The TP4056 can also be set to shutdown mode when there is a power supply, reducing the power consumption to 55uA.
  • The input voltage for the 18650 lithium battery charger board is 5V, with a battery over-discharge protection voltage of 2.5V. The B + terminal is for connecting the positive terminal of the lithium battery, while the B- terminal is for connecting the negative terminal. The OUT + and OUT- terminals are for connecting to the load, such as a mobile booster plate or any other load with positive and negative electrodes.
  • To charge the battery, connect the battery to the B + and B- terminals of the charging board and plug it into a USB female mobile phone charger. A red light indicates that the battery is being charged, while a green light indicates that it is fully charged.
